Frequently Asked Questions

What's the difference between expiration and best quality dates for Rejuvelac?

Rejuvelac does not have a strict expiration date like many conventional beverages. Instead, its quality and taste may change over time. The best quality rejuvelac is typically achieved within a few days to a week of fermentation when it has a pleasant tangy flavor and effervescence. As rejuvelac continues to ferment, it may become more sour and develop a stronger taste. While it is safe to consume rejuvelac as long as it does not show signs of spoilage, the flavor may not be as desirable after an extended period.

How can I tell if Rejuvelac has gone bad?

To determine if Rejuvelac has gone bad, look for any mold growth on the surface, a foul or off smell, or a slimy texture. If you notice any of these signs, it is best to discard the Rejuvelac to prevent any potential foodborne illness.

What are the food safety risks with Rejuvelac?

Rejuvelac is a fermented beverage made from sprouted grains, typically wheat berries or other grains. While the fermentation process helps to develop beneficial bacteria and enzymes, improper preparation or storage can lead to foodborne illnesses. It is crucial to follow proper hygiene practices when making rejuvelac, such as using clean equipment and ensuring the grains are properly sprouted before fermentation. Additionally, ensure that the fermentation process occurs at the correct temperature and for the appropriate duration to minimize the risk of harmful bacterial growth. Individuals with compromised immune systems or certain medical conditions should consult a healthcare provider before consuming fermented foods like rejuvelac.

What are some pro tips for storing Rejuvelac?

To store rejuvelac, it is recommended to strain out the grains after fermentation and transfer the liquid to a clean, airtight container. Refrigerate the rejuvelac to slow down the fermentation process and maintain its quality. It is best consumed within a week or two for optimal flavor and probiotic benefits. If you prefer a milder taste, you can dilute rejuvelac with water before consuming. Remember to use clean utensils and containers to prevent contamination and spoilage.

Any interesting facts about Rejuvelac?

Rejuvelac has its roots in the natural health and raw food movements. It is believed to have originated from Ann Wigmore, a pioneer in the use of sprouts and wheatgrass for health benefits. Rejuvelac is valued for its probiotic properties, which can support digestive health and overall well-being. In some cultures, fermented beverages like rejuvelac are consumed as a traditional remedy for various ailments and as a way to promote gut health.
